Marcus and his twin sister Marci decide to save $25 each week to buy a video console. How long will it take for them to save $675?
Marcus and Marci are saving $25 each per week, so together they are saving $50 per week. To determine how many weeks it will take for them to save $675, we can set up the following equation:
$50 x weeks = $675
Dividing both sides by $50, we get:
weeks = $675 / $50
This simplifies to:
weeks = 13.5
Since they cannot save half a week, we round up to the next whole number. Therefore, it will take Marcus and Marci 14 weeks to save $675.
